- [Be-it knownv that 1, ROBERT VILLIAMS, of Newton in the county ofMiddlesex State of Massachusetts, v a citizen of the United States, haveinyented a new and useful Improvementin Bell-Buoys, of which thefollowing is a specification. I

The problem in bell buoys, especially thosewhich is connected with. the.buoy in the still water at some depth below the surface, but is movablewith relation to the buoy and is detained by its hold on the water asthe buoy moves in either direction.

The present invention relates to improvements in bell buoys of thisclass and it is embodided in a mechanism shown .in the drawings soconstructed that the bell clapper is operatedby the releasing of acoinpressed spring, so that the clapper will al= ways be operated by ablow of given strength. I

The invention will-be understood by reference to the drawings, in ;whichv Figure l is an elevation partly in section of a buoy embodying myinvention. Fig. 2 is a yert-ical section oii the bell and bell operatingmechanism taken on line .2'2 of Fig. 3.; Fig. 3 is a vertical sectiontaken on a plane at right angles to Fig. 2, and Fig. '3 is a section on.an enlarged scale showing one of the stuffing bones-on the main shaft;Fig. i .is a horizontal section taken on line Mot Fig". .2.

A is the float which may be of ordinary construction and is mounted upona tube A to the lower end of which is attached the bell operatingmechanism and bell B. 'C is the case containing the operating rnechanisin. To its lower end is attached the bail A? by which the anchorchain A is attached to the buoy. The lower end of the tube Ais'reinforced by the cap Atwhich sets into it and is riveted thereto,the cap being provided with a flange A which is "Specification ofLetters Iatent.

bolted to the flange C surrounding the upper edge of the case C. Thecase containing the operating mechanism is intended to be filled withoil or other lubricant and for that reason is so put together that thereshall be no leakage. Openings closed by screw plugs 0 are providedthrough which it may be filled. The case O is closed at its upper end asat C and at its lower end is closed by the plate C bolted thereto. Thisplate C containsa central opening through which the operating mechanismis connect-- ed .to the clapper as will be below described. Dowel pins 0assist in. assembling the plate and case.

B is the clapper, the rod 5 of which passes upinto a recess in the plateC and is keyed and pinned to arock shaft B to turn therewith. The rockshaftis mounted in bearings located one on each side of the clapper rod.The lower half 0 of each bearing forms part of the upper side of theplate C A cap-shaped yoke piece 0 forms the top of the bearings and isbolted to the plate Q These parts are provided with a suitable packingto prevent leakage.

As shown the packing comprises rubber washers 72 mounted on the rockshaft B to rotate therewith one on each side of the clapper rod andengaging the bearings. Elastic gaskets I) also or rubber lie between thewashers b and the sides of the upper end of the clapper rod which isrecessed for the purpose. This construction is very desirable becausethe bearings are thus protected from corrosion and the interior of thecase from leakage. A rubber gasket C set into a groove in the uppersurface of the plate C packs'the joint between the plate C and the lowerend'ofthe case To each end of the rock shaft B is also attached aPatented nee. 21, 1915.

rocker arm 13 the plate C being recessed for the purpose. One of theserocker arms is shown in Fig. 3 and both are shown in Fig. 2. Togetherthey form a yoke-like piece. These rocker arms are within the case andare connected by a pin (Z which passes through a crosshead (Z attachedto a rod D, the upper end of which sets into a socket piece D in whichit has slight play. T he socket piece is carried by a 'c'rankpinEsupported between two ratchets F, G, operated'by the pawls f, To theyoke piece 0 is attached an annular plate H to receive the lower end ofthe spring J, this plate 1 be seen thatthe turning of the ratchets F, G,

being also supported on uprights c caston j the plate C The upper end;of the spring, is confined in a four-arm spider H which is screwed ontoa threaded section of'the rod D so that the spring is held under somecompression. The spring tends in expanding to throw the clapper 13against the bell B.

Between the lower end of the socket D and the spider H are a number ofwashers (P so as to adjust the motion of therod D and socket D, withrelation to each other. There should be a certain amount of play betweeni the two however-as will bebelow described. Perforations (Z areprovided to allow for I the draining of the chamber between the closesinto the socket. v From the description so. far glven it will socket andthe end of the rod when the rod will, through the action of the crankpin E in moving from itsuppermost to its lowest position, depress therod D so as to throw the clapper-away from the'bow of the bell and atthe same time compress the spring.

After the crank pin has passed its'lower dead center the springinexpanding will cause the'clapper as shown in Fig; 3 to strike thebell'with a blow of uniform strength due to the force ofthe spring, theclapper being'free to rebound after the blow owing to the yieldingcharacter of the connection between therod D and socket D f Theexpansion of the spring willdrivethe crank pin and the ratchets F,-G,forward,

the crank pin being perhaps thrown by mocrank pin has passed its lowerdead center [it will give a quick throw to ethe socket- --piece andcrank pm and as there 18 1100011- nection between the socket and the rodthe crank pin will be free to turn asfar as its momentum will carry it.

The pawls'f,'g, are four 1n number. Two

are mounted on the plate F and two on the plate G -The ratchet F has ashaft f which turns in a bushing f The pawl plate F also turns on thisbushing f and is pinned to a pinion F also on the bushing f and in meshwith a gear F on shaft M.

The plate F andpinion F are free to turn on the bushing. The bushing f?in which is the shaft 7 is forced into a hub F in the support N attachedto plate C by bolts 0. 'In like manner the ratchet G has a shaft 9?turning in the bushing 9 The pawl plate G free to turn thereon is pinnedto the pinion- Gr which is somewhat smaller than m of soft rubber.

the pinion F and is in meshiwith an idler pinion g on a stu d'mounted inthehub 9* on the support N fastened to the plate 0*. 'This idler g is inmeshwith the gear G" on the shaft M, The bushing g is forced into a hubG on the support N also bolted by bolts c to the plateC 7 By insertingthe-idler 9? between the gears G and G it' will be noted that themovement of the shaft M with its gears F and G in a given direction willcause the,

pawl plates F G 'torotatein opposite di- 7 rections so that-one of thepairs of pawls will act to drive tits ratchetwhile the other I pair ofpawls is ridingfover its-.ratchets teeth to a position where itwillengage them and drive*;tl1'eratchet when the shaft M 1 changes itsdirection of rotation; d

The bearings M for the shaft M project from the opposite'sidesof thecase C and to prevent leakage stuffing boxes M fgof peculiarconstruction are provided through which the shaft Mp'rojectsr Asshownthese stuffing boxes areconstructed as follows. vEach bearingtM isrecessed at its endas at m to'receive aball bearing-which comprises aninner raceway m on theshaft M to receive the balls, andfanother racewaym which sets into the recess and is held therein against a suitableshoulder by an annular plug m which is pinned to the bearing by so ipins-m Against the plug m sets a hard 7 rubber washer m The contactingsurfaces. of these two'parts are smooth sothat the washer m may moveeasily with relation to the plug mi Against the-washer-m is a softrubber gasket or ring m which isicompressed between the washer m anda'washer A pin m connects the hard rubber ,washer'm 'with a lipped platem passing-through the soft rubber washer m in so doing. The diameterof'the 0pening in thefiplate m is somewhat larger than that of the shaftM and is threaded on its interior to'receive the ring mm which screwsinto it and'is pinned to the shaft M. The

plate m has anumber of sockets m inits face andthe ring ml hasa-lugxcarryinga screw m to fit whichevenof these openings it'canregisterwith when this part of the apparatus is assembled. ln setting up thisvpacking, the ring m being fixed to the. shaft M, pressure is'secured'byturning the plate m which advances to compress the various members andis locked by bringing one of the sockets m into registry with the screwm which is then "screwed into it; The hole in t the washer "m -"forthepin m is' 'sufiiciently deep to" allow this adjustment without crowdingthe end of the pin m Motive power is providedlfor, the opera:

tion of thestriker by counterbalanced vanes.

For this purposethe shaft carries at eachend a sleeve Pwhich ispreferably-keyed. thereto by a key'p; aswellas fastenedkby a.

bolt 19 Each sleeve has two sets 9, 1", of

arms projecting therefrom, one set 9 having attached to them the vanes Qwhich may be of any desired shape and the other setcarrying-counterbalances R of sufficient weight to hold-the vanesnormally in horizontal limit, their movement with great violence.

Such action soon breaks'or Wears the mechanism so that it becomesuseless. Such buoys therefore require constant watching and repair. Inthe buoy shown, the vanes may rise into the plane of the axis of thebuoy or even in extreme cases may pass through a complete circle withoutin any way disarranging the striking mechanism. On the contrary duringall this movement the vanes will be performing their ordinary function.This is due not only to the absence of stops but to the use of a gearconnection between the shaft and the operating mechanism. Thecounter-weights serve to bring the vanes back to a normal operativeposition as opportunity offers.

The bell B is preferably attached to the bottom plate 0 of the case bymeans of holders S which are semicircular in shape and are held to thebottom of the case by screws 8. The upper part of the bell is providedwith 'a projecting flange s which lies in the groove formed by the lip sof the holder. A rubber washer 8* lies between, the

top of the bell flange and the bottom of the plate C A rubber ring 8encircles the edge of the flange s and a rubber washer 3 lies betweenthe bell flange and the holder lip 8 These rubber packings serve toprovide an elastic or yielding mounting for the bell so that itsvibration will not be deadened and also so that it will yield slightlywhen struck by the clapper so thatthe clapper will not tend to crack it.

The clapper rod Z) has a peripheral groove Z2 and the clapper proper isattached there to by a pin Zr which passes through a hole in the clapperand engages the rod at the groove. The bell is thus rotatable with rela-I tion to the case so that if its bow becomes worn the bell may beturned slightly to offer a new surface to the clapper. In the same waythe clapper is rotatable with relation to its rod so that as one face ofthe clapper becomes worn it may be turned slightly to offer a newstriking face with which to strike the bell. These features aredesirable in View of the Wear which both bell and clapper receive.

The bell mechanism is operated by wave motion. I The buoy A rises andfalls with the motion of the waves while the vanes Q, because of theirposition and area'serve as a drag and as the buoy rises hold backassuming an angular position with relation to the axis of the buoy, thuscausing the shaft M to turn. As the buoy falls again the vanes assistedby the counterweights R tend to resume their horizontal position and ifthe movement of the buoy is sufficiently great they may pass theirhorizontal position so as to point upward, perhaps even passing avertical position, turning the shaft M in an opposite direction. In aheavy sea however these motions may be exaggerated so that the shaft maybe given a complete revolution, though of course this is not necessaryto the practical operation of the mechanism, nor is it usual inpractice.

Each movement of the shaft M cause an advancing movement to be given toone of the pairs of pawls, j, g, and consequently to the ratchets F, G,and the crank pin E when the crank pin is passingfrom its upper to itslower dead center; the spring J being compressed during this time andthe clapperbeing forced into striking position. When the lower deadcenter is passed the spring not only lifts the rod D thus causing theclapper to strike the bell, but gives the ratchets an impetus which, asthey are free to turn as far as they will go on account of the slidingconnection between the socket piece and the end of the rod D, lifts thecrank pin and carries it by momentum perhaps over its dead center, whenthe pawls immediately catch the ratchet teeth and the wavemotionimmediately becomes effective again to cause the operation of theclapper.

It will thus be seen that the value of this apparatus depends largelyupon the fact that its vanes are free to move in either direction as faras the particularimpulse given by the waves to the float may requirewithout danger of breakage or undue wear in contrast to an apparatus inwhich the moving part has a limit of movement, the result of the use ofstops, whether such stops be protected by bluffers and dashpots or not.Moreover, when a so-called sea anchor is used as a drag, it must be madeheavy and cumbersome to do its work. The van-es de scribed above are notheavy and are both,

filled with a lubricant so that the parts are kept from the corrosiveaction of water and are always in good operating condition.

, This invention is not limited to the precise construction shown as itmaybe otherwise embodied'in its various details. -Moreover certain ofits details may be used in connection with other buoys. The mechanism 18shown in connection with a bell but other forms of signaling mechanismmay besub- SbltlltGCl therefor.

The location of a plurality of. vanes pro- -jecting from the same sideof-ashaft is also new in a mechanism of this general class.
